Phys.org / Life with one less: Engineered bacteria break the 20-amino-acid rule
One of life's many mysteries is how it ended up choosing only a set of 20 amino acids to build proteins for its wide catalog of organisms, from single-celled bacteria to behemoth whales. From a chemical standpoint, many of ...
Phys.org / Colored microplastics could be making global warming worse
There's more bad news about microplastics. We already know they pose a risk to health and can pollute ecosystems, but now researchers have discovered that tiny plastic particles drifting in Earth's atmosphere could be a significant ...
Phys.org / What can singing mice say about human speech?
Speech is a crowning achievement of human evolution, the skill that separates us from every other animal. So, it would stand to reason that evolving this capability required some enormous leap in brain complexity. A study ...
Medical Xpress / New study shows physicians are changing their reasons for leaving clinical practice early
A study published in The Permanente Journal sheds light on what's driving physicians to leave clinical practice early—and how those reasons are shifting. Researchers from the American Medical Association (AMA) analyzed survey ...
Medical Xpress / This everyday plant protein may be quietly reshaping blood pressure risk in ways doctors cannot ignore
A higher dietary intake of soy and legumes is linked to a lower risk of high blood pressure, finds a pooled data analysis of the available evidence, published in the open access journal BMJ Nutrition Prevention & Health.
Phys.org / Plaster-making technique previously attributed to the Romans appears 8,000 years earlier in Motza
Excavations from 2015 to 2021 on the ancient site of Motza, just west of Jerusalem, revealed a sprawling settlement with some surprisingly advanced technology. The site dates back to 7100–6700 BCE during the Pre-Pottery Neolithic ...
Phys.org / Researchers discover a new pathway to building energy-efficient computing chips
The growing popularity of electronic devices—from fitness trackers and laptops to smartphones—is driving demand for more energy-efficient computing chips. Now, researchers have found a way to change the electronic properties ...
Medical Xpress / What is hantavirus? Symptoms, transmission and treatment explained
As an Atlantic cruise ship remains isolated off the South African coast due to a deadly hantavirus outbreak, the world watches with anticipation to learn more about this uncommon but dangerous infectious disease.
Phys.org / When strength in numbers stops working: Climate extremes rewrite monkey society in Costa Rica
As climate change intensifies, scientists are becoming increasingly concerned about how animals will cope with a more unpredictable world. One way to gain insight is by studying how animals have already responded to natural ...
Phys.org / Hourglass nanographenes unlock strong, robust multi-spin entanglement
Researchers from the National University of Singapore (NUS) and collaborators have developed a predictive design strategy for creating graphene-like molecules with multiple interacting spins and enhanced resilience to magnetic ...
Phys.org / How the rise of continents may have set the stage for life on Earth
Earth's earliest continents may have set the chemical stage for life by regulating boron levels in ancient oceans, a new study in Terra Nova suggests.
Medical Xpress / Muscle loss, weak grip and slow walking pace linked to higher stroke risk
Muscle loss, a weaker grip and a slower walking pace were associated with a higher risk of stroke in adults, according to new research published today in Stroke. In the study, people with low muscle strength had a 30% higher ...
